Best Buy was having a sale on DVD-R and DVD+R. It was a 50 pack Memorex DVD-R or DVD+R for 19.99. I got the DVD-R since all the +R were sold out. Well everything was good and I burned 2 movies withought no problem using CloneDVD. Then one day when I stuck a DVD-R disc my dvd-r/rw drive was making noises and sometimes wouldn't eject. I then saw when I went to My computer, instead of saying DVD-RW drive it changed to CD Drive. Sometimes it changes to Removable disc. Now I dont know what could have caused this, but I did come up on this statement [Using new recordable discs (4X for DVD-R) in 1X-2X Pioneer manufactured DVD drives and DVD recorders may cause damage to the DVD drive or recorder and possibly to the loaded 4X disc. The source of the problem is a firmware 'bug' in certain DVD-R/RW drives and recorders, and not with the media itself. A firmware update is required to avoid potential damage to the units and discs.] This was under the 50 pack dvd-r disc. So I was thinking thats the problem and it gave me a link to update my firmware. Well I did update it, but the same thing happens. I tried using the DVD-Rs on my brother in laws computer which has a different dvd-rw drive and different brand of computer, but the same thing happens to his CPU. So Im pretty sure its the Memorex disc. Now does anybody know who to contact to tell them about the problem and hopefully get something back or a solution, cause it sure does suck, now I have 48 non working DVD-Rs.
